Black Mountain Side (2014) is a chilling indie horror-thriller set in a remote Arctic outpost, where a team of archaeologists unearths a strange, ancient structure—and within the frozen silence, they begin descending into paranoia, illness, and supernatural dread. Wrapped in Lovecraftian cosmic horror and The Thing–style isolation, this film explores ancient evils, isolation madness, and the terrifying unknown beneath the ice. Society’s rationality crumbles under the Arctic night’s oppressive dread.

At a site 100 miles from the nearest native reservation, during a Canadian winter, a group of archaeologists have made a startling discovery: The tip of a mysterious, ancient structure, which bears some archaic engravings. The crew, led by Jensen, attempt to decipher it but some mysteries are better left buried.

As they delve further into the structure's origins, things at their camp turn strange. Communications fail, local workers suddenly disappear and the men are stricken with a terrible illness. It's not long before they begin to feel the effects of solitude and then things get really bad...
